Fire Alarm Battery Replacement: Sealed Lead-Acid Specs & Compatible Models
Overview
Fire alarm systems are critical for safety, and the integrity of these systems heavily relies on the condition of their batteries. Regular fire alarm battery replacement is essential to ensure that your fire alarm system remains operational during power outages. In this guide, we will explore the specifications of fire alarm sealed lead-acid batteries, compatible models, and the step-by-step process for replacing these vital components.Importance of Battery Replacement
Fire alarm control panels (FACPs) utilize backup batteries to maintain function when the main power supply is interrupted. The fire alarm backup battery, often a sealed lead-acid type, must be in good condition to provide the necessary power. Failure to replace these batteries on a regular schedule can lead to system failures and possibly non-compliance with safety standards such as UL 268 and FM certifications.Always check the battery's manufacture date. Sealed lead-acid (SLA) batteries typically have a lifespan of 3-5 years. Replace them before they reach the end of their cycle to avoid unexpected failures.
